Description
技术领域 technical field
本发明涉及一种喷头，具体是指一种太阳能电池正面银浆用打印喷头。The invention relates to a nozzle, in particular to a printing nozzle for the front silver paste of a solar cell.
技术背景 technical background
节能和环保是当今世界发展的两大主题。太阳能作为人类取之不尽用之不竭的可再生能源，也是清洁能源，不产生任何的环境污染。在太阳能的有效利用中，大阳能光电利用是近几年来发展最快，也是最具活力的研究领域，研制和开发太阳能电池已经成为当前开发利用新能源的重点方向之一。Energy saving and environmental protection are two major themes of development in the world today. As an inexhaustible renewable energy source for human beings, solar energy is also a clean energy source that does not produce any environmental pollution. In the effective utilization of solar energy, solar photovoltaic utilization is the fastest growing and most dynamic research field in recent years. The research and development of solar cells has become one of the key directions in the current development and utilization of new energy.
晶体硅太阳能电池光电转换效率高，技术也较为成熟，是目前主要的太阳能电池；其生产的关键步骤是在硅片上的正面和背面制作非常精细的电路，将光生电子导出电池。晶体硅太阳能电池正面电极的制备方法有电镀、溅射和丝网印刷等技术。其中电镀法制备的电极质量高，但其成本过高，且制备过程复杂、周期长，另外在电镀过程中可能会使用一些有毒有害物质，存在一定的安全和健康隐患。溅射方法制备的电极质量也较高，但与电镀方法同样存在的缺点是制备成本较高，且制备速度慢。相对于电镀和溅射方法，丝网印刷技术具有设备简单、操作方便、成本低廉、安全无毒、易于形成电极，以及能够得到良好的金属和半导体的欧姆接触，并且表面状态良好的优点。因此，丝网印刷技术已成为目前太阳能电池电极制备的主流方法。Crystalline silicon solar cells have high photoelectric conversion efficiency and relatively mature technology. They are currently the main solar cells. The key step in their production is to make very fine circuits on the front and back of silicon wafers to export photogenerated electrons out of the cells. The preparation methods of the front electrode of crystalline silicon solar cells include techniques such as electroplating, sputtering and screen printing. Among them, the electrode prepared by the electroplating method is of high quality, but its cost is too high, and the preparation process is complicated and the cycle is long. In addition, some toxic and harmful substances may be used in the electroplating process, which has certain safety and health risks. The quality of the electrode prepared by the sputtering method is also high, but the same disadvantages as the electroplating method are that the preparation cost is high and the preparation speed is slow. Compared with electroplating and sputtering methods, screen printing technology has the advantages of simple equipment, convenient operation, low cost, safety and non-toxicity, easy to form electrodes, good ohmic contact between metals and semiconductors, and good surface conditions. Therefore, screen printing technology has become the mainstream method for solar cell electrode preparation.
目前采用丝网印刷技术制备获得太阳能电池正面电极的细栅电极高度一般在10-30μm、宽度在60-180μm之间。上述栅线存在以下缺陷：(1)较宽的电极栅线导致较大的电极遮光面积；(2)较低的金属电极高宽比导致较大的电极电阻损耗。上述缺陷的存在会导致太阳能电池的电流收集效率降低并致使光电转换效率出现下降。因此，要获得具有高光电转换效率的太阳能电池，就必须减小栅极线宽和提高栅电极的高宽比。传统的丝网印刷工艺通过增加栅线条数的网版设计来进行电极印刷以降低串联电阻，但增加了栅线的条数后需要将栅线的宽度相应减小才不会产生较大的电极遮光面积；然而要将栅线宽度进一步变小，同时还要保证栅电极的高度，传统的丝网印刷工艺很难达到。在传统丝网印刷工艺基础上，一些研究者公开了中国专利CN 101447531A(公开日20090603)与中国专利CN 101807627A(公开日20100818)，通过在丝网印刷过程中引入电镀和溅射等工艺，能制备获得较细和较大高宽比的栅线，但由于引入了电镀和溅射等工艺，其生产成本也大幅度提升。还有一些研究者公开了中国专利CN 201868440U(公开日20110615)，通过设置细栅线在宽度上40-90μm的渐变结构，来实现减小遮光面积和降低串联电阻，从而提高太阳能电池的光电转换效率，但由于仍然没有改变栅极的制备方法，其作用有限。At present, the height of the thin grid electrode for the front electrode of the solar cell is generally 10-30 μm and the width is 60-180 μm prepared by screen printing technology. The above grid lines have the following defects: (1) wider electrode grid lines lead to larger electrode light-shielding areas; (2) lower metal electrode aspect ratios lead to greater electrode resistance loss. The existence of the above defects will reduce the current collection efficiency of the solar cell and lead to a decrease in the photoelectric conversion efficiency. Therefore, in order to obtain a solar cell with high photoelectric conversion efficiency, it is necessary to reduce the gate line width and increase the aspect ratio of the gate electrode. The traditional screen printing process uses a screen design that increases the number of grid lines to print electrodes to reduce series resistance, but after increasing the number of grid lines, the width of the grid lines needs to be reduced accordingly so as not to produce larger electrodes However, to further reduce the width of the grid line and ensure the height of the grid electrode, it is difficult to achieve by the traditional screen printing process. On the basis of the traditional screen printing process, some researchers have disclosed Chinese patent CN 101447531A (public date 20090603) and Chinese patent CN 101807627A (public date 20100818). By introducing processes such as electroplating and sputtering in the screen printing process, it can A thinner grid line with a larger aspect ratio is prepared, but due to the introduction of processes such as electroplating and sputtering, its production cost is also greatly increased. There are also some researchers who have disclosed the Chinese patent CN 201868440U (publication date 20110615), which reduces the shading area and reduces the series resistance by setting the fine grid line with a gradient structure of 40-90 μm in width, thereby improving the photoelectric conversion of solar cells Efficiency, but because the preparation method of the gate is still not changed, its effect is limited.
